15. Dissolved Oxygen Setup

Use Setup Dissolved Oxygen mode to customize the parameter. Press

from the measurement screen and then press ENTER when DO% or DO (mg/L)

is selected for percent saturation or concentration modes respectively. Note that

setup parameters differ slightly depending on which is selected.

Sample ID

This is a user selectable number from 1 to 99999.

Incorporating a sample ID to identify one or more

data points is useful to distinguish data that is

saved into memory or sent to a PC or printer. Use

the up/down arrow keys to adjust the values and

left/right arrow keys to move the cursor.

Offset Cal (% saturation only)

Use this feature to offset the meter’s value to

another DO meter. Using the % saturation mode,

observe the reading a sample solution after it has

stabilized. Similarly, observe the reading of the

same sample using another DO meter as a

reference. The probe of the reference meter should

be immersed in the same sample at the same

depth.

The DO 2700 allows ±10% offset adju

stment. Note that subsequent user

calibrations will reset the offset adjustment back to the factory default value of 0.0

% offset.

Pressure Unit (% saturation mode only)

Select mmHg or kPa pressure units.
